OPERATING INSTRUCTIONS SOHN MODEL 6503FLEXOGRAPHIC LABEL PRESS

To begin set-up of the Model 6503 Flexo Printer, refer to the threading diagram. There are threeconfigurations that can be used. Follow these instructions for proper results.

The next step would be to center the paper to maintain proper tracking. The center of the model6503 machine is 4" from the back plate. An example would be when using 2" wide material, a mark shouldbe put on the center of the roll at 1" from either edge, place the roll on the unwind spindle with the paperunwinding to the left from the top of the roll and measure 4" to the mark on the material from the back sideplate. The material now is centered on the machine. Next thread the material thru the machine, refer tothreading diagram. The spring loaded pacer assembly must be unlocked when threading. To unlock, pullback on the assembly until the pin locks in the back side plate. Once you have the paper threaded, place theblank core on the unwind, attach the material to the core. At this point, the measurement of 4" is againapplied. Next the paper guides are set both on the infeed and rewind, the 4" measurement again is applied.Slide collars to edge of paper allowing approximately 1/64" clearance on either side. This will assure propertracking of materials. Run machine to test for proper tracking of material.Pacer roller should be engaged atthis point.

The printing plate is affixed to the proper circumference print cylinder using .015 stickyback.Making sure the corresponding correct gearing is used. It is then inserted into the top of the print stationmaking sure that the proper shaft, gear and print cylinder are utilized and the corresponding bearing blocksin the right direction are used. You will find on the bearing blocks themselves, numbers from 61 to 91, (32D.P.), 32 to 53 (1/8 C.P.) in one configuration and then reversing or turning the blocks upside down, you willthen be able to read from 91 to 122, (32 D.P.), 53 to 74 (1/8 C.P). This is necessary because of the largerange from 6" to 12" circumference that can be utilized on this particular press.

The bearing blocks are then put so that the T is to the inside of the machine, meaning that thebearing blocks are T shaped and that the wider part of the bearing blocks are to be facing the center of theunit itself. This will assure proper alignment of the gear, shaft, and print cylinder. At this point, considerationshould be given to the mounting of the printing plate on the print cylinder so that you do have someadjustment horizontally on this shaft.

To accomplish this, there are two brass set screws in each print cylinder. Care must be taken thatthis print cylinder is not torqued too tight so that the brass allen head set screw does not become rounded.Brass is used so that scoring of the anvil shaft, scoring of the print cylinder shaft is eliminated. If steel setscrews are used, scoring of this shaft will occur which will cause difficulty in making the finer adjustmentsthat will be needed to center the print both horizontally and vertically with the cutting die.

The screws are added to the hold down for the bearing blocks and tightened. The two knobs nowcan be tightened to bring the print cylinder and printing plate so that the printing plate just barely touches thepaper. Care must be taken to assure that the anvil shaft gear and the print cylinder shaft gear is meshed.Next, insert the ink fountain being sure the fountain is tipped back to assure that the ink does not run out thefront of the ink fountain. Slide the fountain forward on the fountain rail assembly until it comes in contact withthe stops. Then lightly tighten the lock screw to hold the fountain in place.

In turning the unit on, a count must be on the counter in order for the unit to continue running. Themain on/off switch must be on, the toggle switch must be in run position, and the run jog button depressed toinitiate the running of the motor. The speed control can now be turned on and gradually brought to a highernumber so the unit will start revolving slowly. At this time, the ink fountain adjustment knob to the right of theunit is to be turned slowly, advancing the ink fountain. (Care should be taken so that the ink fountain gearand print cylinder gear mesh smoothly.) Continue advancing the ink fountain until the printing plate picks upa slight even coating of ink completely covering the printing plate image, observing the print quality at thistime.By depressing or relieving the adjustment screws, the ideal impression can be achieved. After theimpression has been set satisfactorily, insert the cutting die ( ) again checking the gear for the right

5

number of teeth to match that of the die and print cylinder and insert the bearing blocks and die into the diestation making sure the die blocks are put with the T to the inside of the machine. Next, place the die bearerhold down into die station locking into place with the 4 hex nuts. Adjust die to print image.

It is recommended to disassemble and clean the fountain at end of job.

1. Remove ink fountain from machine and place on flat surface. Loosen Dr. Blade screws.2. Remove the four brass thumb screws and take cover off.3. Remove Dr. Blade assembly (inspect for need of replacement).4. With a 3/32 allen wrench, loosen the set screws on the left and right side of the ink roller.5. Remove the shaft and gear assembly from the ink fountain (pry with screwdriver if necessary).

1. Wash in Type C Cleaner when using water base ink.2. Rinse in water. Dry with paper towel.

To reassemble, reverse the disassembly process. A fountain line-up tool (T-bar) should be used toassist you in realigning the ink roller.

1. Insert the gear and shaft assembly on the left side of the fountain body (as the front of the inkfountain is facing you).

2. Slide the "O" ring first, then the retainer onto the shaft.3. Insert the T-bar on the right side of the fountain body.4. Slide the "O" ring first, then the retainer onto the T-bar.5. Place the ink roller between the retainers on the left and right side. Align the shaft of the gear and

shaft assembly into the roller on the left side, and the shaft of the T-bar into the roller on the rightside.

6. Push the gear and shaft assembly completely through, replacing the T-bar shaft.7. Lock the set screws on the roller (there are two flat areas on the shaft. The set screws should be

tightened on these flat areas).8. Put Dr. Blade assembly into fountain.9. Replace cover and tighten with four brass thumb screws.10. Put a small amount of pressure on Dr. Blade screws.

***********

The ink fountain is the heart of your printing machine. Use a regular cleaning schedule and keep thefountain away from lint and dust. Extreme gear wear and bad printing can often be traced to a dirty fountain.Inspect the doctor blade regularly and replace if excessive wear is apparent.

It is recommended that the ink fountain be returned to the factory for inspection and maintenance ifexcessive wear or malfunction is apparent.

ORDERING INFO FOR PRINTING PLATES FOR MACHINESUSING PRINT CYLINDERS AND DIES.

In general terms, the necessary information for ordering plates for the above machines can bestated as a description of the printed image (text, graphics and color separation information), specificationsfor distortion, step and repeat corresponding to the tooling that will be used and an indication of the runningdirection of the image.

The description of the image can be specified through the use of a printed sample, sketch and/orlisting of the necessary copy. In any case, it's important that the information be clear, concise and legible.Long listings of text should be typewritten if possible. For multi-color work, information indicating colorseparations should be included. Information concerning special graphic elements like bleed borders andspecial color overlap should be stated explicitly.

The necessary details concerning tooling information follow:

1. MODEL OF MACHINE.

2. NUMBER OF COLORS FOR JOB.

3. WIDTH OF THE DIE CUT in the direction across the web. (This will be the width of the paperstock in the case of butt cut labels.)

4. LENGTH OF THE DIE CUT in the direction along the length of the roll.

5. INDICATE THE SHAPE OF THE DIE CUT. This might be BUTT CUT, RECTANGULAR(INCLUDING SQUARE), ROUND, OVAL, OR SPECIAL SHAPE. In the case of therectangular die cut we will also need the SIZE OF THE CORNER RADIUS, most commonly1/8" but many dies have either a smaller or larger corner radius. In the case of an oval orspecial shape it's essential to have actual samples of the labels cut by the die in questionsubmitted with the plate order. If the sample of the die cut has been printed it should bemarked "SAMPLE FOR DIE CUT ONLY".

6. THE NUMBER OF ROWS OF CAVITIES ACROSS THE DIE. Most often this number will be1, but in the case of smaller die sizes this could be any number between 2 and 10 or more.In the event that this number is greater than 1 we will also need some indication of theSPACING BETWEEN THE CAVITIES IN THE DIRECTION ACROSS THE WIDTH OF THEWEB. THIS CAN BE THE ACTUAL SPACE BETWEEN THE CAVITIES OR WHAT WE CALLTHE "CENTER DISTANCE ACROSS THE WEB" WHICH IS THE SUM OF THE WIDTH OFTHE CUT ACROSS THE WEB PLUS THE SPACING TO THE NEXT CAVITY ACROSS THEWEB.

7. THE NUMBER OF ROWS OF CAVITIES AROUND THE PRINT CYLINDER. This is usuallythe same as the number of rows of cavities around the die.

8. THE NUMBER OF TEETH ON THE PRINT CYLINDER TO WHICH THE PLATES WILL BEAPPLIED. Most often this number will be the same as the number of teeth stamped on thecutting die used, BUT NOT ALWAYS. It is possible to use an integer ratio between thecutting die and print cylinder. For example, it is common practice to use a 54T print cylindercarrying a 1 cavity image with a 108T, 2 cavity butt cut die. In this case the print cylindermakes 2 revolutions to every 1 revolution of the die. If you are ordering plates for this type ofsituation it's a good idea to spell it out completely.

14

9. THE PITCH OF THE GEARS IN USE "32DP" or "1/8CP".

Specifications of the direction of the printed image should be made using the industry standardunwind specification chart. Lack of this specification is the single most cause of plates that are made inerror. In the event that the chart cannot be used to indicate the proper image direction, be sure to indicatethe proper orientation with a sketch or marked-up sample.

All the above looks tedious at first glance, and initially gives the impression that a complex orderform must be used. The disadvantage to using a form is that purchase orders from customers will readsimply "ONE LOT OF PLATES PER FORMS ATTACHED" and all references to the real specifications willbe lost forever on following documents like P.O. file copies, work orders, invoices and packing slips. This isvery confusing particularly when working indirectly with users through dealers and distributors. In practiceit is a simple matter to put all that information into a reasonably short sentence type sequence.

For example:

Plate for Model 6503, 1 color, per copy submitted for address labels, for 1.25" x 2.00" rectangledie cut, 1/16" corner radius. 2 across on 1.50" centers, 3 around on 65T/32DP, Unwind #4.

or as another example:

Plate for Model 6503, 1 color, per artwork submitted for carton labels, for 2.00" x 5.25" butt cut,1 across 1 around on 54T/32P, Runs with 2 cavity butt cut die on 108T/32DP, Unwind #4.

Please take special note that it is a standard policy in our industry to ALWAYS INDICATE THEDIMENSION ACROSS THE WEB FIRST in a size statement. In the first example above the standardimplies that "1.25" is the dimension across and that the "2.00" is the dimension around the die and along thelength of the roll. In the second example, since it is a butt cut, the standard implies that the "2.00" is the webwidth and that the "5.25" is the dimension around the die and along the length of the roll.

REORDERS for plates of this type should include all the specifications as listed above AND shouldinclude a reference to the SOHN INVOICE NUMBER on which the plates were last produced. Allcompleted jobs are filed by this number. Many customers request reorders based only on a verbaldescription of the image on the plate. It is impossible to search through hundreds of items for a specific itemin this manner and guarantee that the proper plate will be produced.

SLITTER HEAD: Slitting is accomplished by removable blades held in the head by pressure from theoutboard locking screw. To insert blades, loosen the locking screw and position the spacers asrequired and insert the blades in the groove. Also insert a blade at the inside end of the spacers whereit will serve as an edge guide. Tighten the locking screw. The blades may also be cut in two andinserted vertical to the web.When slitting paper, the web normally slides across the top edge of the slitting head. When slittingpressure-sensitive tape, the head should be adjusted downward to provide 1/16" clearance betweenthe head and the web. Vertically mounted blades can be used on this operation.
